Refusing to fix the mistake MTN made

Mtn sold me a contract for 24 months at 189 a month. As stated over the phonecall they made to me all calls are recorded. When i recieved my first statement they gave me a statement for 36 months. After sending multiple emails and getting responses they started sending me a generic email stating i do not meet channel support requirements (after they gave me a case number and responded to me) They refuse to give me the recording wich is my consumer rights to have and they refuse to respond to my emails MTN this is what you call *****ing and if you do not fix the problems i will go to court.
